The Amnesia Collection contains both titles from the series, which are Amnesia: The Dark Descent and Amnesia: A Machine for Pigs. The first game in particular is highly regarded by both critics and fans of the horror genre. A Machine for Pigs, which is an indirect sequel, wasn't as well-received but is still a decent title.

The series' gameplay mechanics rely primarily on stealth to avoid dangers, and not giving the player any weapons to defend themselves has become a prevalent mechanic in the genre.

Normally, the Amnesia Collection costs $34.99, but if you head over to the Steam page right now, you can grab it for free - which is a great deal, especially if you missed the earlier Humble Store offering. Due to what appears to be a temporary bug, some gamers are seeing the individual games available for free, but the collection still listed as $34.99. In such a case, you can navigate to the individual game's page to get it for free.

It is important to note that the offer lasts for a limited time only. However, if you manage to get the titles for free during this unspecified time period, the games will be listed in your library permanently.
